To promote the use of EHR data for clinical research in China, OHDSI China Working Group, together with Zhejiang University, is going to host the 2017 OHDSI China Working Group Workshop. The conference will invite top experts and scholars from both China and US to present state-of-the-art work in both informatics methods (e.g., deep learning, common data model, natural language processing, data privacy and security) and EHR-based clinical studies, thus to promote adoption of OHDSI in China and to enable international collaboration,​ education, and training in biomedical informatics.
